CLEVIS.

Application filed October 7, 1915.

To all whom it may concern the clevis pin is removably, yet securely locked in the clevis.

Another object of the invention is the production of an improved locking clevis inexpensive and simple in construction, and thoroughly dependable in operation.

With these and other objects in view, the invention consisting in the construction, combination and novel arrangement of parts, will be fully understood from the following description, reference being had to the accompanying drawings, which form a part of this application and in which like characters of reference indicate corresponding parts throughout the several views, of which Figure 1 is a side elevation of a clevis constructed in accordance with the invention; Fig. 2 is a plan of the same, the clevispin being omitted; Fig. 3 is a transverse section of the same, taken through the eyes of the clevis; and Fig. 4 is a perspective view of the clevis pin.

Although I have illustrated and hereinafter described the preferred embodiment of the invention, I would not be understood as being limited to the specific structure chosen for the illustration, for various alterations in the details of construction and arrangement of parts, may be made without departing from the spirit and scope of the invention as defined in the appended claims.

Referring, now, to the illustrations, 5, represents the bow of the clevis, which isof spring material and includes arms, 6 and 7, formed at their ends with eyes, 8 and 9, respectively. The eyes are mutually alined Specification of Letters Patent.

Serial No. 54,534.

and encircle a clevis-pin 10, threaded into the eye, 9. The clevis-pin is formed with a square, or flat-sided head, 11, which may be formed integrally with a thumb-grip, 12, for conveniently manipulating the pin.

The outer face of the eye, 8, is provided with a square or flat-sided recess, 13, adapted to receive the correspondingly-shaped head of the clevis-pin.

To insert the clevis-pin, the arm, 6, of the bow is first sprung inwardly, as indicated in dotted lines in Fig. 1, and the pin then threaded into the eye, 9. The pin is then turned to a position where the head thereof will .be received by the recess, 13, when the arm, 6, is permitted to assume its normal position, and thus prevent rotation of the pin.

It is apparent that prior to unscrewing the clevis-pin to remove it, the arm, 6, must again be sprung inwardly as previously stated.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is

1. An article of the class described comprising a clevis-bow having inwardly-yieldable arms each provided with an eye, and a pin removably inclosed by said eyes, said pin being threaded into'the eye of one of the arms and provided with a head, adapted to be normally engaged by the other arm to Patented Sept. 5, 1916.

prevent rotation of the pin, and disengaged from the latter arm when either arm is sprung inwardly.

2. An article of the class described comprising a clevis-bow having inwardly-yieldable arms, each provided with an eye, and a pin removably inclosed by said eyes, said pin being threaded into the eye of one of the arms and provided with a flat-sided part, the other of said arms having a part normally engaged with said flat-sided part to prevent rotation of the pin, and disengaged from said fiat-sided part when either arm is sprung inwardly.

- In testimony whereof I have hereunto set my hand.
